Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment device with a coagulant quantitative adjustment function. Background Technology

[0002] In the treatment of municipal sewage and industrial wastewater, coagulation and sedimentation are the core processes for removing suspended solids, colloidal particles, and some dissolved pollutants. This process involves adding coagulants to aggregate tiny pollutants in the water into large flocs, which are then separated by sedimentation or filtration. This can achieve a suspended solids removal rate of 80%-95%, laying the foundation for subsequent biological or advanced treatment.

[0003] Existing technology discloses a wastewater treatment device with coagulant quantitative adjustment function (publication number CN222042851U), relating to the field of wastewater treatment technology. The device includes a treatment tank, with a feed hopper rotatably mounted on the top of the tank. A toothed ring is fixedly mounted on the outer wall of the feed hopper. A drive mechanism is located on the top of the treatment tank and on one side of the feed hopper, and a first L-shaped rod is driven and connected to the drive mechanism. The toothed ring is also driven and connected to the drive mechanism. This invention, through its drive mechanism and connecting mechanism, enables vertical movement of the two stirring rods during rotation, thereby effectively expanding the stirring range and improving stirring efficiency.

[0004] The aforementioned wastewater treatment device with coagulant quantitative adjustment function can use the elastic force of two elastic telescopic rods to squeeze the first annular plate, so as to intermittently block the lower end of the feed hopper during the up-and-down movement of the first L-shaped rod, thereby achieving the purpose of intermittent quantitative feeding. However, the aforementioned wastewater treatment device cannot control the area of ​​the empty tank for liquid inlet, nor can it control the amount of coagulant fed per unit time, resulting in poor performance during use, which needs to be improved.

Pre-treatment can be carried out before treatment, which can enhance the treatment efficiency and achieve good results. Attached Figure Description

[0025] A wastewater treatment device with coagulant quantitative adjustment function includes a treatment tank 1, a wastewater inlet pipe 2 on the right side of the treatment tank 1, a control valve 6 inside the wastewater inlet pipe 2, a wastewater discharge pipe 5 at the bottom right side of the treatment tank 1, a coagulant quantitative addition component 3 at the top of the treatment tank 1, and a treatment component 4 inside the treatment tank 1.

[0026] The coagulant quantitative addition component 3 includes a feed pipe 301, a connecting pipe 302, a control pipe body 303, a fixed baffle 304, an inner connecting frame 305, a magnetic column 306, a magnetic slide 307, an extension column 308, a control baffle 309, and a holding member 310. The feed pipe 301 is fixedly connected to the top of the treatment tank 1, the connecting pipe 302 is fixedly connected to the top of the feed pipe 301, the control pipe body 303 is fixedly connected to the top of the connecting pipe 302, the fixed baffle 304 is fixedly connected to both sides of the inner ring of the control pipe body 303, the inner connecting frame 305 is fixedly connected to the front and back of the inner ring of the control pipe body 303, the magnetic column 306 is fixedly connected to the top of the inner connecting frame 305, the control baffle 309 is fixedly connected to the top of the magnetic slide 307, and the extension column 308 is fixedly connected to the control baffle. At the top of the control baffle 309, the pull member 310 is fixedly connected to the top of the control baffle 309. The bottom of the magnetic slider 307 has a circular hollowed-out groove, the diameter of which matches the diameter of the magnetic column 306. The magnetic slider 307 is slidably connected to the top of the magnetic column 306 and magnetically connected to the magnetic column 306. The magnetic slider 307 and the magnetic column 306 are magnetically connected and can be magnetically locked after adjustment. This allows for timely locking after adjusting the position of the control baffle 309 and the fixed baffle 304, ensuring the normal use of the device. The pull member 310 has a through groove inside, the diameter of which matches the diameter of the extension column 308. The pull member 310 is designed to facilitate the user to pull and rotate the control baffle 309, adjust the overlap area with the fixed baffle 304, control the liquid inlet, and achieve good results.

[0027] Preferably, the processing component 4 includes a motor 401, a stirring blade 402, a guide plate 403, a connecting frame 404, and a filter plate 405. The motor 401 is fixedly connected to the front of the processing tank 1, the stirring blade 402 is fixedly connected to the output shaft of the motor 401, the guide plate 403 is fixedly connected to both sides inside the processing tank 1, the filter plate 405 is fixedly connected to the top of the connecting frame 404, the connecting frame 404 is fixedly connected to the top of the guide plate 403 and they are close to each other at one end, and the inner wall of the guide plate 403 is provided with a strip-shaped groove.

[0028] In use, wastewater to be treated can be introduced through the wastewater inlet pipe 2. Before introducing the wastewater, the control valve 6 needs to be opened to ensure the wastewater flows in. Then, coagulant for treating wastewater can be added from the top control pipe 303. The amount added needs to be measured, which requires adjusting the overlap area between the control baffle 309 and the fixed baffle 304. When the control baffle 309 and the fixed baffle 304 do not overlap at all, the inlet flow rate is the lowest, close to zero. To increase the amount of coagulant entering, the holding member 310 can be held and the control baffle 309 can be rotated. During rotation, the magnetic slider 307 can be attached to the magnetic suction column 30. The top of baffle 6 slides to adjust the overlap area between the control baffle 309 and the fixed baffle 304, increasing the overlap area. This creates an empty slot, allowing coagulant to flow in. The flow rate can be controlled by adjustment, resulting in good performance. A treatment component 4 is installed inside the treatment tank 1. After the corresponding amount of coagulant is introduced, the motor component 401 can be started to drive the stirring blade 402 to rotate. When sewage enters, it enters from both sides and falls onto the top of the guide plate 403. Under the guidance of the guide plate 403, it flows and then passes through the filter plate 405. Pre-treatment can be performed before treatment, which can enhance the treatment efficiency and result in good performance.
